The Ardor multichain platform has several quantity units: ARDR, unitsQNT, priceNQTPerShare, priceNQTPerCoin and rateNQTPerUnit for representing all tokens within the platform. The parent chain ARDR is used to provide the proof of stake algorithm for all the system. Like all currencies, ARDR circulates in the system, moving from one user to another by payments and purchases. Also, a small fee is required for every transaction, including those in which no ARDR is transfered, such as simple messages. This fee goes to the owner of the node that forges (generates) the new block containing the transactions that are accepted onto the blockchain.
